ANTISKIDDING DEVICE FOR AUTGMO'BILES.

Application filed April 23, 1924.

To all 10. mm 2'15 may concern:

Be it known thatl. Amos A. TYSON, a citizen ot the United States, residing at Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in rintiskidding Devices for Automobiles, of which the tollowing is a specification.

My invention relates to an anti-skidding device adapted to be attached to vehicle 7 wheels. The device is preferably made in sections which may be attached separately to the wheel, each section engaging one or more spokes. The sections consist of arched plates adapted to rest on the inner periphery ot the wheel telly while short pieces of chain are secured to the plate sections and thrown over the rubber shoe of the wheel.

One advantage of supplying the device in. sections is that the short pieces of chain may easily he replaced it worn out or broken without disturbing the other pieces of chain. Another advantage resides in the fact that when the device is made in three or four sections the weight to be handled. is considerably reduced and the anti-skidding device may'accordingly be attached or detached in a much shorter time and at a greater convenience than usual.

In ordinary chains of this class it takes considerable time to straighten out the chains and take out all kinks before putting them on. This is entirely avoided in the present invention. It one of the'short pieces ot chain should happen to break it may immediately be removed without disturbing the rest ot the anti-skidding device.

In the accompanying drawings, one embodiment of the invention is illustrated, and

' Figure 1 is a fragmentary side elevation of a vehicle wheel with one section of the anti-skidding device attached;

Figure 2 is a top plan view of one of the sections adapted to engage three spokes and shown developed;

Figure 3 is a side elevation of a section adapted to engage a. single spoke;

Figure at is a side elevation of a section engaging two spokes;

Figure is a transverse section along line 5-5 of Figure 1 and in larger scale.

Figure 6 is a detail of a securing bolt.

In the drawings. reference numeral 10 represents a hub oi a vehicle wheel with Serial No. 708,475.

radiating spokes 11, telly 12 'and rubber tire 13. V

Y As illustrated in Figures 1 and 2, a section engaging three spokes ot a wheel is shown.

This section consists of two symmetrical narrow plates lt and 15 arched to the contour of the inner periphery of the telly, which plates abut along their inner edges, as at 16. These plates may be made of sheet metal or cast and in order to make the attachment as light as possible an aluminum alloy is preferably used. The total width across the two plates corresponds substantially to the width of the telly 12 and at intervals along the outer edges of the plates are furnished lugs or narrow guard members 17, said lugs being formed by bending down portions of the plates. The lugs engage over the sides of the telly, as best seen in Figure 5, and their purpose is to protect the, telly from the rubbing of the short pieces of chain 18 which are laid around the rubber tire 13. Each piece of chain terminates with a snap hook 19 of any suitable shape which is intended to engage in eyelets 20 which are preferably riveted, as at 2]., on the inner side of each section 14 and 15 and set transversely to the side edges of the plates. It will be evident that when the chains are attached to the eyelets they will never be able to injure the telly as they do not come in direct contact therewith, but, instead, rest on the lugs 17.

Along the inner edges of the plates are shown halt sockets 22 and 23 shaped to fit together around the outer ends of the spokes, as indicated in lligure 1. These halt sockets have corresponding cars 23 with suitable apertures for securing bolts 24-. The bolts are threaded and adapted to receive nuts 25 and between each nut and the corresponding car 33 is inserted a spring washer 26 which, when the nut is drawn up tightly, will prevent its unscrewing.

In Figure 3 is seen a section of the device adapted to engage one singue spoke 27 and is provided with eyelets 28 for two chains instead of tour as indicated in the above described figures. The construction of this device is in other respects the same as that described in connection with Figures 1 and 2.

In Figure 4 is shown a section having two socket-s 29 for two wheel spokes, and three pairs of eyelets 80 for three pieces of chain. In all of these sections a rubber or tell:

lining 31 is preferably inserted between the outer periphery ofeach section and the adjacent face of the telly, as best seen, in Figure 5 of the drawings.

Previous to attaching the device on a Wheel, the chains may be hooked onto their respective eyelets 20 and the two plates 14 and 15 closed in over the telly so thattlie sockets 22 and 23 engage around the spokes. The bolts 24 are then inserted and drawn up tightly by their nuts.

Another manner of attaching the device on a 'WllCGl would be to have the short chains loose and secure theplates l and 15, as before, to their spokes when the plates vill The chains may be left in that position. thereupon beattachedone by'one to the eye lets and when not needecbdetached in the same manner While theplates are left in position. In thatcase, the eyelets 20 may be provided with latch springs orthey may be constructed as snap hooks, see Fig. 5.

Having thus described the invention, What is claimed as .neW is:

1. An anti-skidd ng wheels comprising a member fitting the inner,

periphery ,of the telly and divided along a medialhne in the plane of the Wheel, means on said member for securing it to the spokes, gripping members adapted to fold over the tire,.elements on said first member adapted to hold saidgripping members in position, andspacedlugs, along the outer edges. of said member overhanging the device for vehicle sides of the telly and forming guards for said gripping members. I

2. in anti-skidding device for vehicle Wheels comprising a member fitting the inner periphery of the telly and divided along a medial linein the plane of the Wheel, means on said member for securing it to the spokes,

gripping members adapted to fold over the tire, elements on said first member adapted to hold said gripping members 111 position, and spaced lugs along the outer edges 0t said memberoverhanging the sides of the telly line, ears on said half sockets, bolts engag-s ing in said ears and adapted to tighten the sockets around the spokes; spaced lugs along the outeredges of said sections overhanging the sides of the telly, an eyelet on said sections adjacenteach of said lugs, and chains detachably secured in corresponding eyelets, said chains being adapted to fold over the tire while engaging with said lugs.

In testimony whereof I aiiix my, signature.
